T0 @ZZ whom, :it may concern:

Be it known that I, CHARLES RAW, of Graytown, county of Ottowa', Stateof Ohio, have invented new and useful Improvements in Butter-Churns; andI do hereby declare that the following is a full, clear, and'eXactdescription of the invention, which will enable others skilled in theart to which itappertains to make and use the same, reference being hadto the accompanying drawings and to the letters of reference markedthereon, which form part of this specification.

My invention relates to a butter-chu rn, and has for its object toprovide a stoneware crock having formed upon its edge a concentric ringprojecting outward beyond the edges thereof and form upon the under sideof the ring a concentric upwardlyprojecting groove, whereby theclosure-plate having the driving mechanism mounted thereonimay bereadily and tightly secured to the crock, and which closure-plate,together with the mechanism for fastening the same to the churnbody andthe driving mechanism mounted thereon, may be veasily and quicklyremoved from the churn-body, leaving a regular stoneware crock withoutmechanism or metal fastened thereto.

A further object is to provide adrivingcrank adapted to be removablymounted upon the driving-arbor.

The invention further consists of the elements hereinafter described andreferred to.

In the drawings, Figure l is a perspectivel View of my invention withthe churn-wall partially broken through to show interior. Fig. 2 is alongitudinalsection through a churn constructed in accordance with myinven tion. Fig. 3 is a cross-section on the line a: w, Fig. 2. Fig. 4is a top plan view of the churn-body, and Fig. 5 is a fron televation ofa locking-bolt. p

The object of my invention is accomplished by providing a stonewarecrockmolded, preferably, to the form of churn-tubs now in use, and byconstructing the tub out of stoneware I have found that a butter may beproduced of a sweet odor and the tub can be more easily and thoroughlycleaned.

I have found that in a churn-tub constructed of wood the butyraceousfluids more or less permeate the wood through its pores, causing an odorto eminatetherefrom even after repeated scourings, whichaect andcontaminate fresh butyric globules formed in the tub by churning andwhich objection is wholly obviated by my invention. I have also found'that a stoneware crock having ears formed upon its sides is difficult tohandle, as it cannot be rolled without the danger of nicking or breaking0E the ears, and, further, that the ears weaken the crock at the pointof adhesion, which objections are obviated by my invention, a concentricring being less easily broken than ears. A concentric ring has thefurther functions of a hoop or strengthening-ridge and of being used asa grip or handle for lifting purposes. I have also foundthat a crockconstructed in accordance with my invention may be more thoroughly andeasily cleaned than one having ears and means for fastening the coverpermanently secured to such ears.

l designates a churn-crock molded in aecordance with my invention andprovided with a concentric enlarged rim 2, which has formed upon itsunder side an upwardly-pro jecting groove 3. The closure 4t has securedthereon in a central position a journal-plate 5, in which are revolublymountedthe horizontal driving-arbor 6 and a vertical driven arbor 7.Motion is transmitted from the driving to the driven arbor by means ofintera meshing mitergearsS 9. TheV driven verti cal arbor projectsdownwardly beyond the closure-plate and has secured thereon. in apendent position by a set-screw a couplingsleeve 10, having its upperend adapted to receive the arbor and prevent lubricating-oil escapingtherefrom into the churn, andat its lower end is provided with anangular socket adapted to receive the angular paddle-arbor l1, to whichthe paddles 15 are secured in helicoidal relation. `The foot of thepaddle arborll is stepped in a socket 12, formed by a depressionintegral with the bottom of the crock, and is in vertical alinement withthe receiving-socket secured to the arbor '7. By this construction theclosure t, with the op erating mechanism secured thereto, together withcoupling-sleeve 10, may be removed from the churn Vessel separate fromthe paddle-arbor 11, and after removing closure 4 sleevelO may beremoved from arbor 7 and loo separately cleaned of anyoil or the likevac-V cumulated therein. By the use of sleeve as.

Projecting inwardlyfrom the wall of vessel 1 Y and integral therewithare breakers 13, which operate to break up the centrifugal currents`produced -by the revolving paddles. These breakers are tapered at theirlower endsto their connection With the wall to allow the bottom paddle15, whichY is provided with a lip 14, adapted'for the purpose, to reachinto the angle formed by the Wall and the bottom,

whereby the cream that ordinarily remains vundisturbed therein, as Wellas the main body of it, is evenly agitated when the paddle-arbor isrevolved.- By the spiral arrangement of the paddles a constant upwardcurrent is produced, which assists in gathering. the butas they areformed at the top of the iluid. v 4 i The top closure is secured to thechurncrock by means of bolts 16, having integral `therewith elongatedheads 17, projecting in opposite direction from the body p0rtion18 andare adapted to enter the groove formed upon the vunder side of theenlarged rim.

19 designates notches formed upon the periphery of the rim, adapted toreceive the vertical stem of the bolts,which project upwardly above therim through plates 20, provided 2 f A`cargoes@ With orifices toreceivethe bolts.. The plates 2O are suitably secured to the top closure andthe bolts tightened by means of thumb-nuts y21, and by means thereof theclosure is drawn against the ledge 22, concentric with the rim andformed thereby..

VWhat I claim is- The butter-churn herein described, comprising anearthenware vessel having its top edge provided with an interior annularledge 22, for receiving and supportinga cover for the vessel, andthebottom with socket 12, and having formed integral therewith verticalbreakers 13, and a concentric exterior rim'2, provided with a concentricgroove 3 on its under side, and vertical notches 19 in its periphery; atop closure 4, having projecting plates 20, provided with bolts 16,having heads 17, and thumb-nuts 2l; a shaft 7 mounted on the cover 4,and extending centrally through it, Aprovided with gear mechanismadapted to rotate it; a coupling-sleeve lO, and a paddlearbor11,p`rovided with paddles; all constructed, combined and operating asshown and described. j

In testimony that I claim the foregoing as my own l hereby aiIix mysignature in the presence of two witnesses. V
